Background and Purpose: Taking into account the scarcity of research on Syrian refugees from the perspective of sociolinguistics, this research explored Syrian refugees’ reasons for dialect preferences when they communicate in various domains of life in Jordan. Methodology: The study employed a sequential mixed-methods design, which involved collecting both quantitative and qualitative data. The quantitative data were collected using a questionnaire of 20 items. Qualitative data were collected using the semi-structured interviews which were conducted with 18 Syrian refugees. While the quantitative data analysis was done using descriptive statistics, the transcripts of the semi-structured interviews were coded and analysed thematically. Findings: The results of the study showed that the majority of Syrian refugees use the Syrian Dialect with family members, Syrian friends, and colleagues at work, and Syrian neighbours. Further, the results revealed that most of the Syrian refugees prefer to use the Jordanian Dialect when they communicate with Jordanian neighbours and friends, and with Jordanians at the workplace and in educational contexts. The study revealed that the major reasons for dialect preferences among Syrian refugees are a desire for integration, close connection to their families, a sense of cultural familiarity, comfort in communication, interlocutors, and the importance of the formal context. Contributions: The findings of this research can contribute to research in sociolinguistics in terms of understanding the Syrian refugees’ dialect preferences.
